    Inverter In RV Not Grounded?

    Again, thank you so much to all. I believe I am beginning to understand. I have ordered the Giandel 2200W 12V inverter. It has a permanent 3-wire connection for higher power-required service that includes a ground connection. It also has a case ground connection and I previously added a chassis...

    Inverter In RV Not Grounded?

    Since I am now thinking that downsizing is smart for my limited inverter needs, I am focused on the Giandel 2200-watt unit (the one without the built-in solar charger controller) instead of a larger 3000-watt unit. I'd love to throw my very limited budget to the wind and buy a supposedly higher...

    Inverter In RV Not Grounded?

    I looked at the EDECOA, and have it on my list. But, I am now thinking/learning the 3000-watt size is probably overkill for my needs? When you say it runs your 10K BTU AC with no problem, what type AC is that. The little portable 6000 BTU AC unit I looked at draws 930 watts/10.4 amps which is...

    Inverter In RV Not Grounded?

    Thank you. I just read the page about grounding three times, and some of the rest of the Samlex manual. I do not understand it all. And, further, an expensive inverter like a Samlex or Victron is not in the budget for me. I recognize they may be better quality over the long term, but I am a...

    Inverter In RV Not Grounded?

    I appreciate the recommendation. And, I am beginning to understand the value of a 24V system. But, that's not really in the cards for me with my very limited barely-beginner knowledge level. Further, and perhaps more importantly, I am learning I don't really need a 3000-watt inverter, at all? I...

    Inverter In RV Not Grounded?

    Thanks again. Yet, my limited knowledge still leaves me slightly confused. So, I've just read another hour's worth of posts on this forum, and I admit a little hopefulness in the fact that I am not the only beginner having trouble with explanations here and asking for comments to be "dumbed...

    Inverter In RV Not Grounded?

    Good morning, again, Since I responded (above) earlier today, I've been reading more on this DIY Solar Forum and other sites. Given that the unit I bought two weeks ago now shows up on Amazon as "unavailable," I've decided to just return it and buy something else. One of the appeals of the...

    Inverter In RV Not Grounded?

    Duh. Obviously needed info. Sorry. It is a XIJIA 300W 12 Volt Pure Sine Wave Inverter. Bought on Amazon, link: https://www.amazon.com/dp/B07VBGM3T6?psc=1&ref=ppx_yo2_dt_b_product_details. Note: When I just connected to that link on Amazon, it shows a different photo than 2 weeks ago, and now...

    Inverter In RV Not Grounded?

    Again, I’m a real beginner. I just spent another 4 hours over two days reading info on this forum, and now I am even more confused. Yes, I read "Mobile Grounding Made Simpler . . . and several other threads about RV/mobile inverter grounding, one with a lot of technical debate was waaaaay over...

    Different Type Batteries Connection Risks?

    Thank you, thank you. That explanation is VERY helpful. I appreciate your time. I am seeing the picture much more clearly. It appears I need to find some larger distribution blocks, as mine are only 4 posts. I will tackle the rewiring and additional battery connection this weekend. And, never...

    Different Type Batteries Connection Risks?

    A life interruption kept me from responding faster. My apology. I very much appreciate both perspectives about my issue. To Northernchateau: You wrote exactly my fear and my reason for asking the question. For perspective, my choice is (a) either to limp along with only one 200 Ah LiFePO4...

    Different Type Batteries Connection Risks?

    I just spent nearly two hours reading related posts here. I am a limited knowledge beginner. I have learned a lot from this forum. But, I still don't understand one nagging issue in my mind. A quick recap: - Early this year I had four (cheap) Chinese 150Ah LiFePo4 batteries fail, i.e. would not...

    Update. Replacement BMS? What's next?

    (1) Since I have none of your (sophisticated-to-me) tools, I have not tried to test and make the checks you suggested above. But, I kinda' understand what you are saying. And, since I am now in an RV park with 30 amp power, I am not microwave-less. But, I will test this weekend with shore...

    Update. Replacement BMS? What's next?

    Hedges, I owe you an apology for the long delay in responding. Please accept my heartfelt "I am sorry." I've had several travel issues with my RV over the past few weeks. I've read your last message at least a half-dozen times over the past couple of weeks, hoping a read on a different day...

    Update. Replacement BMS? What's next?

    Thank you, once again. 1) High resistance connection between cable and breaker. If that is the case, should be hot enough to burn your finger. I'm not sure I truly understand "high resistance connection?" (Beginner here.) I have 4/0 AWG with heavy copper lugs. There is a total of 18" length...

    Update. Replacement BMS? What's next?

    Good afternoon, Thanks, again, especially for the encouragement. I ran the inverter/microwave test this afternoon wiring the battery directly to the inverter. The microwave ran for 1 min 10 sec and then the system shut down. It turns out my brand new ($80) 200 amp breaker (Blue Sea/Buss...

    Update. Replacement BMS? What's next?

    Good evening, folks, The break I took was good for my mental attitude, but I need to get my system running correctly so I am starting up again. Everything is working well except the microwave which will not run, as before. Please note it is not the "start-up" of the microwave that causes the...

    Update. Replacement BMS? What's next?

    Good morning, Thanks to both of you for the responses. Have to hit the road this morning (6:30 am here) so this info quickly . . . Yes, you are misreading my wiring. Total "runs" in test configuration with everything else disconnected are 18" (w/ 6 lug connections + bolt-on 200 amp fuse at...

    Update. Replacement BMS? What's next?

    Good morning, To the best of my ability, I've completed all the tests I'm capable of. The results are below. Is it possible I am learning that a single 12-volt 200 Ah LiFePO4 battery does not have enough start-up oomph to run a 3000-watt inverter with an 1100 watt microwave (rated 1550...

    Update. Replacement BMS? What's next?

    OK, folks, I sincerely appreciate the education and information. I've conceded a kindergarten-level beginner hasn't got a snowball's chance in h--- of getting everything correct when setting up, and especially finding problems!!! Questions answered: -- microwave power input rating is 1550 watts...

    Update. Replacement BMS? What's next?

    Thanks again to all. Had to take some time away from my electrical mess. Yes, the 2 gauge wire is directly from the genset to the batteries. I never thought about it much (because it was the least of my worries), but, yes, the only purpose of that wire should be to start the generator. The...

    Update. Replacement BMS? What's next?

    Thanks again to all for the continuing help. I'm taking a day or two off for other issues. My mind is boggled with all this new stuff and electrical system problems. It is all still very frustrating because of my lack of basic knowledge and difficulty understanding some of the terminology and...

    Update. Replacement BMS? What's next?

    Thank you again. So, I am back to checking both the new solar DC wiring and the old RV DC wiring . . . still without really understanding how to do that? "Might be easier to disconnect existing DC wiring and run a fresh wire from battery to your high-current load." I don't know what you mean...

    Update. Replacement BMS? What's next?

    It is all very depressing. And, I still have not gotten past Google searching from several posts early yesterday -- trying to understand abbreviations, what things are, and how to do suggestions, one-by-one. Basic things that are instantly recognized and comprehended to most of you are all new...

    Update. Replacement BMS? What's next?

    Bad has gone to worse, it seems. Bottom line, there is clearly something seriously amuck somewhere in my electrical system, and I do not know how to find it? Because the whole system crashed again this afternoon when running only the TV (10 amps), ice maker (10 amps), and chargers for phone...

    Update. Replacement BMS? What's next?

    Thank you again. I ordered the Eastman Bussman BUSS brand 200 amp breaker from Blue Sea because they had it in stock for arrival to me Thursday (after that I will be boondocking and in the middle of nowhere AZ so I can't receive packages). I think I also have learned: (1) ANL fuses are not...

    Update. Replacement BMS? What's next?

    Thank you again, very, very much. But . . . . . . If it is not one thing . . . This morning, I blew the 175 amp breaker on the main 4/0 cable from the battery to the inverter? That never happened (with my old 450Ah battery array before failure)? I decided to try my small electric coffee...

    Update. Replacement BMS? What's next?

    . . . (from previous post) . . . it made a great buy for me because of the 4-day UPS shipping (when UPS doesn't screw up). I was desperate and I had to have a U.S. inventory battery. The price for the Lynx package was very competitive with others (stocked in U.S.) -- $550/100Ah, $1050/200Ah, I...

    Update. Replacement BMS? What's next?

    Thank you. I will leave everything as is. Your help is exceedingly helpful and reassuring. But, a curiosity. I'm looking at the Bluetooth settings right now, and my mind cannot quite grasp how to set up " . . . at freezing stay below a couple of amps in, at 40, limit to 10 amps, etc."? That is...

    Update. Replacement BMS? What's next?

    I found the DALY Smart BMS app, but it would not load from the Android Play Store onto my Samsung S10? Tried and tried. Finally decided it must be blocked by some setting in the S10? I then pulled out a 6-year-old LG phone and loaded the app there with no problem, finally. Got it connected...

    Update. Replacement BMS? What's next?

    I think I am OK on the short fat wires. I have 4/0 AWG (previously connecting the three failed batteries/BMS, 9" there) and 4/0 AWG from the battery (one for the moment) to the inverter, about 18" total with an on/off switch and a 175 amp breaker inline from the battery to the inverter. Correct...

    Update. Replacement BMS? What's next?

    Well, those two posts are a big curveball to me. So, first, I need to figure out how to connect to the Daly Bluetooth? No instructions came with the battery & BMS. Is there an app? How does that work, if anyone knows. I will now start searching for Daly BMS user information. Supposedly the BMS...

    Update. Replacement BMS? What's next?

    WOW! OK, I am trying to absorb all of that. Paragraph #1 -- I need to read it another half-dozen times, but beginning to understand. Paragraph #2 -- Again, re- re-read required. Not sure how to "pull power" for a test. But, do I even need to do so? I'm OK just buying a BMS, wiring it in, and...

    Update. Replacement BMS? What's next?

    I checked and got exactly the voltage readings you expected. Then, just to double-check, "in order" means 3.35V is cell #1, 6.7V is cell #2, etc. Correct? Thank you for that suggestion and informattion. That is incredibly helpful. Thanks again. I think I may be beginning to understand the...
